POSITIVE-ACTION ROTARY-VALVE PUMP.

Application filed m 21., 1924. Serial 10.121335.

This invention relates to pumps and has for an object to provide apositive-action, deep well, rotary valve pump.

An additional object is to provide a low speed rotary pump designed tobe bodily set in a deep well hole, and an object is to provide drivemeans whereby to eliminate friction of contact due to any weight of thepump shaft extension.

An object is to provide a rotary-valve, deep well pump of most simpleform and compact parts most of which can be probeing to provide a pumpof such design and 5 organization as to require but very little machinedressing or finishing.

Another object is to provide a pump of approximately cylindrical form sothat it may be readily lowered in a naked orcasedgo well hole. In thisconnection an object is to provide for the mounting .of the pump as aunit and joint device between the usual suction pipe and the dischargetubing so that a pump of maximum size can be used within the hole. Thatis, to provide a pump of such design that its working elements are of asize nearly equalling, in overall dimension transversely, the diameterof the hole or casing.

manifest in the following specification of an embodiment of apparatus ofthe invention shown in the accompanying drawing; it being understoodthat other modifications,

\5 variations and adaptations may be resorted to within the scope of theinvention and the spirit thereof as here claimed.

The present invention pertains to a type of pump embodying a disc-likerotor 2 the cylindrical periphery of which has a suitable number, fourhere, of radial teeth or blades 3 which, preferably, have thickenedbases 4 to obtain strength. At each end of the rotor is a gear 5; theseparts being fast More objects and advantages will be made on a stubshaft 6 having hearings in end hole. duced from round stock metal; an.object For economic construction, the meeting endfaces of the shellparts 7-8-11 are ground flat and smooth to meet tightly andare fastened'by through bolts 12.

A set of twin discs 13 are disposed in peripheral contact with eachother on the medial plane of the periphery of the rotor 2 and alsotangentially in contact with said periphery. (Flgs. 1 and 2) these discsforming valves having shafts 14 in parallelism and being radial to therotor shaft 6. The valve shafts have bushings 15 countersunk in seatstherefor in the contiguous faces of shell parts 7-11, 811; these partsbeing pocketed or cut out to receive the interposed valves.

The rings 11 surround the gears 5 and these are in mesh with bevelpinions 16 fixed on the shafts 14 so that the valves and the rotor areturned in'unison and here timed two rotations of each valve to onejofthe rotor. The rings 11 are shown as over lapping the margins of the endfaces of the/- rotor and so form a closed annular fluid space in whichsweep the teeth or hlades'3, which run close to the house 10.

,The rotor here has four blades 3 and to clear these -at regularintervals the valves 13 have marginal pockets 17, which obvious- 1y arecut or machined out to closely inter mesh, gear-fashion, with the rotorteeth.

Fluid flow into the shell is had through an mlet port 20 in the bottom 7and its near ring 11, thence into the blade'chamber in house ring v1O;the inlet being disposed on the side'of the valves from which the bladesrun away, Fig. 3. Any blade running away from the valves causes asuction on its rear side and liquid is drawn into the space between theleaving blade and the valves. Liqiud trapped between the blades iscarried around until it is brought adjacent to an outlet port 21 in head8 and its near rin 11. Since the contacting valves 13-13 b o ck flowliquid is expelled at the outlet with positive force by blade 3approaching the valves.

The pump has a discharge conduit 23 1n the present case forming a pumptub1ng leading from the well hole in which the pump is submerged. Thetubmg includes a suitable number of sections coupled by collars 25 (onebeing shown). A collar is here threaded onto the threads 9 of the endblock 8; this havinga gland 26 through which extends the stub shaft 6,this havlng a squared end 6.

A feature of my invention conslsts of means for driving the pump shaft 6without throwing any weight of the driving -means on the running partsin the shell,

thus reducing friction thereof and avoiding rapid wear whichnecessitates pulling the pump from the well for renewals. The drivemeans includes a drive shaft consisting of sections 28 having squared(or other non-circular) ends to match the sockets in the ends ofreversible couplings 29, only one of which is shown. The coupling has acylindrical body rotatively fitted in a bearing 30 which is provided ineach coliar 25.

Around the hearing are provided flow passageways 31 for liquid passingthrough the pump. Each socketed coupling 29 has a medial girdle 29 withfaced ends to bear on the upper ends of their coupling bearing whichthus form supports as well as bearings of rotation. The weight of eachshaft section is taken wholly by its lower coupling and bearing.

The lowermost coupling (of a series) receives the stub shaft end 6.

Since each section of the extension shaft is supported on its owncollar-bearing there is no tension created in the string and as eachsection is" detached or free from the next no binding tendency resultsfrom any disa-lignment of the shafting in a deephole.

The sections .of tubing 23 are joined by collars 25 in the lowermost ofwhich the pump body is screwed, and on the lower end of the pump body isscrewed the perforated suction pipe 33. The discharge tubing,

the pump body and the suction pipe are of substantially the samediameter and for a given well hole will be of a diameter just smallenough to freely pass into and from the hole. The diameter of the pumpis practically determined by the over-all diameter of the rotor with itsblades plus thethin pactness and structural design. Usually pump tubingscrews up right-hand and I show, by arrows, a right-hand rotation ofpump shaft and rotor so that torque of action tends to tighten up thejoint.

It is obvious that a machine of this type 1s workable as a motor whenfluid is suppl1ed thereto under pressure as the driving medium.
